Simply wait for the previous coat to dry to the touch before applying the next coat. For heavy coats, wait for 12-24 hours between applications. The amount needed may vary depending on the surface roughness, so make sure to use all the material to achieve a long-lasting membrane. To ensure optimal results, avoid applying the sealant under hot and intense sunlight.
Also, remove any painters tape while the sealant is still wet for a clean finish. In some ponding situations, the membrane may turn brown due to surfactants. However, this will dissipate over time as the water cycles and cleans. Cleaning up after application is a breeze.
Simply use soap and water or mineral oil to clean your skin. This waterproof sealant is perfect for DIY enthusiasts, contractors, and homeowners who are looking for a versatile and effective solution for all their leak repair needs.
